摘要
阐述了状态空间平均法的基本思想,通过引入开关函数,建立了串联型有源电力滤波器的数学模型,利用状态空间平均法建立了单相电路状态空间平均模型.用Matlab仿真软件对状态空间平均模型进行了仿真,结果表明状态空间平均模型准确性能够满足要求,具有一定的合理性.
The state-space average method (SSAM) is described.The mathematical model of series active power filter is built through the introduction of switch function,and the state-space average model of single-phase circuit is built through SSAM.Matlab as a simulation software is applied to simulate the state-space average model.The simulation results show that the state-space model can satisfy the required accuracy,so it is reasonable in a certain way.
